This depends on how git was build (on compile time configuration).
git-instaweb.sh (source of git-instaweb) has

        PERL='@@PERL@@'

which is set to value of $PERL_PATH (or, to be more exact, its squoted
version) during building git-instaweb.  So you can simply use

  $ make PERL_PATH=/usr/bin/perl
  # make PERL_PATH=/usr/bin/perl install

or whatever, or you can use ./configure script

  $ make configure
  $ ./configure --with-perl=/usr/bin/perl


On Linux for example the path to perl is set explicitely, instead of
using "/usr/bin/env perl" construct.  The 'env' construct has the
following disadvantages:
 - it uses first Perl find in your $PATH, so if git works for you or
   don't work depends on user's personal configuration
   (reproductability, convenience and security).
 - AFAIK it doesn't allow to pass switches to Perl


P.S. Check if you have new enough Perl (there are problems with
Unicode support in old Perl), and if you have CGI.pm new enough
installed for gitweb.
